Disclosure context

About kazu

The Kazu ransomware group is a relatively new threat actor that emerged in November 2025, operating with apparent financial motivations based on their targeting patterns across multiple sectors and geographic regions. Given their recent emergence and limited public documentation, details about their country of origin and potential affiliations remain unclear, though their targeting of diverse international victims suggests either a ransomware-as-a-service model or an independent operation with broad reach capabilities. With only nine documented victims to date, specific details about Kazu's attack methodology, initial access vectors, and encryption techniques have not been extensively documented by major threat intelligence organizations, though their targeting spans healthcare, public sector, financial services, and technology organizations across the United States, Colombia, South Africa, Nigeria, and Great Britain. The group's recent emergence means there are no widely reported major campaigns or high-profile incidents documented by established security research organizations like Mandiant, CISA, or the FBI. As of the latest available intelligence, Kazu appears to remain active given their very recent first observation date, though their limited victim count and recent emergence make definitive assessments of their operational status preliminary. The group has been linked to 23 public disclosures across our corpus. First observed on a leak site on November 11, 2025; most recent post August 23, 2026. The operation is currently active.

If your organisation is affected

A listing by kazu means Canada Yocale: Appointment Management System appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

  • Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
  • Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
  • Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
  • Report the incident to your national CERT, CCCS (Canada), as required for your jurisdiction.
  • Monitor for the data appearing on kazu's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
